Abstract

The present invention relates to a method for grinding structural components, such as stone or concrete columns or slabs. According to the invention, the structural components are set in motion in relation to each other with their surfaces in contact with each other, to create a grinding effect through the movement.

Description

A kind of Ginding process

The present invention relates to a kind of Ginding process, particularly a kind of member that can be used for use in the building, for example post, plate and similar component carry out abrasive method.

Traditionally; the pillar of concrete and stone or plate are with the abrasive disk of rotation or grind band and grind; being with in these abrasive disks or grinding has artificial corundum or other abrasive particle or grounds travel; and diamond more and more commonly used, as will soon to become unique use material; for example, just announced a kind of method of using diamond to grind concrete cylindrical in No. 90842, the Finnish patent.

All use diamond to carry out abrasive method all is expensive.Therefore and cost is high the technology solution of in addition announcing in above-mentioned patent not only is difficult to implement and, but also is easy to damage, and the someone comes operational outfit always.And once can only grind a pillar.

Germany's number No. 12332 patents have been announced a kind of Ginding process, and according to the method, a cylindrical work can be ground with second cylindrical work.This structure and method require that grinding cylinder is separately arranged, and the grinding cylinder that these separate is also expensive naturally and be easy to wear and tear, and must change and repair, thereby cause considerable fringe cost.

According to this method of the present invention can be by simple equipment, be used to the post or plate and the similar component that obtain polishing, and need not diamond lap or the grinding cylinder that separates, this method can also once be ground several posts or several plates by means of simple device.This method contacts with each other together them simultaneously by means of making member produce relative motion to each other simply.For the situation of pillar, this that is to say and make pillar rotate relatively to each other, thereby makes their own grindings mutually.And, then make their mainly to each other do linear relative motion for the situation of plate, the apparent surface of plate is polished.

But work in-process adds abrasive to increase grinding effect.But for instance, concrete column or plate self just contain grinding mineral materials.

Therefore, disclosed this method can allow some posts or harden lump together, and grinds simultaneously, and the gained result still is a size product quite accurately, and these products need not be monitored especially from phase grinding.

Characteristics of the present invention are set forth in the appended claims.

Below with reference to respective drawings example of the present invention is described, in the accompanying drawings:

Fig. 1, Fig. 2 and Fig. 3 represent some pillars are lumped together the different modes that grinds;

Fig. 4 and Fig. 5 represent to arrange two examples of position to grind of plate.

Among each figure from Fig. 1 to Fig. 3, numbering 1 expression post, numbering 2 expression chain or like instrument, this apparatus is suitable for post is combined, and for example, connects sprocket wheel or similar device by the center at post.Arrow is represented direction of rotation.Obviously, chain is driven by a motor or other suitable driving arrangement, but for brevity, driving arrangement is not shown among the figure.

Self-evident, can make these pillars rotate in many different modes.In other words, can drive each independent pillar, perhaps as mentioned above, make all pillars that will be ground rotations with one or same equipment with the separate equipment of any kind.In both cases, all be that these pillars are suitably rotated producing speed difference on their outer surface, or producing reverse rotation (in fact these pillars are rotated) on the contact point of these pillars on same direction.

As mentioned above, the present invention is applicable to grinding highlightedly, for example, and concrete column, but obviously, if work in-process adds certain grinding-material, all of other also can use like an elephant some such materials of metal.In this case, this grinding-material is finished actual machining work.

Fig. 4 and Fig. 5 have represented a kind of mode of abrasive sheet 3.Particularly two or more plates can be stacked together, make these plates generation relative motions to each other with a kind of suitable apparatus then.For example, a kind of possible arrangement is to make following plate keep motionless, and makes top one or several plates move to the left side or the right (or other any direction) of shown position.

Making a kind of possible mode of one or several plate motion is to handle cylinder by a kind of medium of pressurization.Plate 3 is placed between the cylinder, makes plate 3 motions by operating the cylinder that is positioned at the side of will moving successively.Another kind of suitable alternative is fixedly upper cable or analog at the edge of plate, with these hawsers the plate front and back is spurred.

If seem necessary, available a kind of suitable mechanical device is adjusted a post or plate to another post or plate applied force.In fact this means that these posts or plate are pressed together to each other simultaneously, or they contact to each other and are suitably alleviated.Obviously, can significantly change the intensity of abrasive action like this.

The present invention can be with multiple mode correct, and does not deviate from basic conception of the present invention or by protection domain that claims limited.

Claims

1. method that resembles post, plate or similar component especially for grinding, these members by, for example, stone or concrete are made, it is characterized in that making these members (1,3) to move to each other and simultaneously make them contact with each other, ground simultaneously owing to this contact makes contact surface.

2. according to a kind of method of claim 1, it is characterized in that situation, make post (1) around its longitudinal axis rotation, and they are ground in the vertical each other for post (1).

3. a kind of method corresponding to claim 1, characteristics are the situation for plate (3), make plate (3) the linear or nonlinear relative motion of intercropping each other, grind each other to make its apparent surface.

4. according to a kind of method of claim 1, it is characterized in that adding in the method the grinding-material that mixes mutually with water or certain other medium.

5. according to a kind of method of claim 1, it is characterized in that acting on the own wt of the lip-deep grinding pressure of post or plate from post or plate.

6. according to a kind of method of claim 1, it is characterized in that increasing or reduce the power that acts between the member (1,3) according to the grinding effect that will reach.

7. according to a kind of method of claim 1, it is characterized in that in the method, in the apparatus such, used cylinder or the similar device handled by the medium of pressurization to give member kinetic energy such as sprocket wheel and chain.
